I did a little too much in part A, you're right. nothing else was provided in the problem statement though. Is there any reason why one estimation would be more accurate than another method of estimation?

A = plot(sin(T*2*pi*W+1E-8)./(2*pi*W + 1E-8)); A.Parent.XTick = [0:100:1000]; A.Parent.XTickLabel = {'0', '0.1', '0.2', '0.3', '0.4', '0.5', '0.6', '0.7', '0.8', '0.9', '1'};

Maybe declare T somewhere?

Not sure if this helps exactly, but if it's specifically a MATLAB report, there is a *publish* option that will export all codes triggered and output in command window along with a table of contents.

Summary:: Hello there, I'm a mechanical engineer pursuing my graduate degree and I'm taking a class on machine learning. Coding is a skill of mine, but statistics is not... anyway, I have a homework problem on Bernoulli and Bayesian probabilities. I believe I've done the first few parts...

Hello there, please help if you are able.. So we have a tank with input volumetric flow and output volumetric flow The system is controlled by the height of water in the tank h(t) = hdes + (√h(t))*(-A2*(√2g) / A1) - h'(t) I am trying to find a transfer function for this system but I do not...

That is very good news! They take forever grading the tests and I just really wanted some positive feedback. If it's not too much to ask, would you tell me if I did the second question correctly too? There are only 2 questions so I promise this is the last one!

Hello there. I took a test yesterday in my thermal fluids 1 class and I was hoping somebody could confirm or critique my answer. (Don't worry, I asked the professor first if I could take the picture) The problem is: Water is pumped from a lake to a pool through a 0.05 m diameter pipe. System...

Hi there So we have a group design project in my mechanical systems 2 class and it basically goes as follows: design a mechanism to cut a half inch aluminum bar in half using a standard hacksaw blade and 4 AA batteries. You have to use a motor w/ input > 5000 rpm for the 'main' component we...

Homework Statement The uniform 5 m-long round wooden rod (ρ = 800 kg/m3 ) is tied to the bottom by a string with length 1 m. Determine the inclination angle θ if the water level is 3.5 m. What if the water level is 7m? Homework Equations Fb = ρgV The Attempt at a Solution So I'm really...

It may appear as capacitance but I'm pretty sure that a capacitor does not create it's own electricity... this has an anode, a cathode, and an electrolyte. When photons hit it, it releases electrons and those are being stored somewhere. Maybe it acts like a capacitor but as an entire unit, it's...

Hello there everybody In my research group we've been working on PV cells and exploring non-conventional techniques to try and raise the efficiency of some of the lesser explored materials that have PV potential. Well, last week while testing one of our cells in a solar simulator, we noticed...

Is that correct?

That was actually my other attempt before I decided to post. I divided the atoms in a BCC cell by Avogadro's number and got 3.321*10^-24 Mol Then I was going to multiply that by each molecular weight, respectively, to get their masses I just didn't want to follow that thread and be sure of it...

Homework Statement So for my homework assignment in 'Materials Science and Engineering', We were given the following problem. 1. Li and Ra both are both BCC metals. For this problem assume they form a complete solid solution (even though the very large difference in their atomic size tell us...
